A self-driving car from Tesla Motors (NASDAQ:TSLA) would be considered legal in 45 states at the moment, according to analysis from Wired.

The self-driving issue is likely to be teed up politicians and regulators over the next year as Tesla's new software update pushes up the timetable on the autonomous car concept.

In Germany, for example, an explicit ban exists on autonomous driving.

Another riveting puzzle: How does the software code get tested?

There's also the question of what the insurance industry will have to say about the burgeoning technology and how much advanced sensor components will cost.

The air Pollution index in China has hit dangerous levels this week with Beijing registering a 168 today and Nanjing hitting a shockingly high 288 yesterday (extremely unhealthy).

Other cities with an "unhealthy" reading on air quality include Guangzhou, Nanjing, Maanshan, Chengdu, Chuzhou, Zhenjiang, Yahgzhou, Wuhu, and Hong Kong.

Reports indicate the Chinese population has become more concerned about the medical ramifications of long-term exposure to pollution.

The other side of the equation is the restrictions placed on car sales in certain regions in the nation.
